i installed my wb 255 fuel pump and now my fuel pressure is 56psi at idle and wot. is that normal?



here is my set up:
t3 turbo
12:1 fmu
xs power ic 24x12x3 3in inlets and outlets
2.5 ic piping
2.5 down pipe and exhaust
drag manifold
xs power wastegate 8.9 spring
b&m fuel press reg.
STOCK injectors
STOCK fuel rail

 

what kinda injectors are those?

 

You are using a 255 high pressure pump right? well if so you will need an aftermarket Fuel pressure regulator, the fackory cannot keep up. I have the same pump and i use the aem fpr, works great. B&M Makes a kit to mod your factory FPR to be adjustible. hope this helps

 

im using stock injectors



i do have a b&m fuer press reg and 56psi is the most it will turn down

what psi am i supposed to be at?

 

i think around 35 to 45 at idle and the fpr disconnected frorm a vacum source. my guess is that you going to have to buy a better fpr. i had the same problem with my factory reg untill i bought a aftermarket one

 

no need to worry about it, when you get tuned the tuner can compensate for the higher fuel pressure. if you dont plan on tuning then the extra pressure is good. stock setting w/out vacuum line hooked up is 31-41psi.

 

if im running at 56psi wont i foul out my plugs?

 

not if its tuned to run 56psi, crome has a feature that allows for fuel pressure changes. not sure about the rest of the software.

 

i dont have any way to tune except for a fuep press reg and it wont turn down. i dont have a afc,emanage or hondata or anything. will it be safe to drive?

 

.... i wont answer that.
